NDU is highly valuable when you are running 24x7 environments with live active data. We have had alot of success with this but still prefer a scheduled upgrade downtime if possible. Both work great. :)

NDU really isn't is it? CIFS connections are still severed and NFS survives both an NDU and a reboot easily enough.
I've never understood the value of NDU honestly but if someone has a success story I'd be interested to hear it.
Thanks.

As you have clusters, I would recommend first updating to 7.0.6 and then - if required - to 7.2.3 or whatever version is available at this time. Then both of them are NDU. NDU between major releases are supported first starting with 7.2.3 and minimal base release is 7.0.6.
Personally I do not see any point jumping through 7.1 additionally.
Otherwise update from 7.0.4 directly to 7.2.3 was quite straightforward.

Hi guys,
I'm currently running a number of FAS940 clusters with DATA ONTAP Version 7.0.4 (Sun Feb 5 00:52:53 PST 2006 )
Primarily NFS with some ISCSI.
I'd like to hear back from you re your experiences upgrading to the current s/w releases available on the NOW Site for the FAS940
series system.
http://now.netapp.com/NOW/cgi-bin/software?product=Data+ONTAP&platform=FAS940.
Our immediate options are to take a small step to 7.0.6, move up a little further to 7.1.2.1 or go for the latest and greatest, 7.2.3.
Have you guys seen any issues along the upgrade path to any of the above releases?
Looking at the stats there are a decent number of systems running 7.2.3, however the average run-time days per system
is quite low.
Feedback appreciated.
Thanks,
Philip
